    • 5.0 out of 5 stars Works so far in Synology 1821+
Size: 32gb Color: 2 x 16GB
The Synology brand is really expensive compared to this. I have been buying OWC memory for years so I trust this one. I am no expert but this has been working great so far. I don't see any issues unless Synology can somehow detect the brand of memory and disable it.

    • 5.0 out of 5 stars Can't believe I did it myself!
Size: 64gb Color: 2 x 32GB
Wow. Once I view the video on how to change out memory, I thought I might be able to do it myself. These RAM modules fit perfectly and worked first time. I'm so glad I looked into adding more RAM. My stock 16GB was almost constantly full and causing all kinds of problems. I had no idea what to do... I thought I would have to buy a new iMac. Then I somehow stumbled into the idea of adding RAM and saw that it was pretty do-it-yourself. This RAM saved the day for sure. I replaced two stock 8GB modules and put in two 32GB. And I think my iMac is running faster too. ... show more

    • 5.0 out of 5 stars Great quality memory
Size: 64 GB Color: 4 x 16GB
This worked great with my iMac and found it very easy to install. If you want to learn how to install this memory in the rear of the Apple iMac - there are several videos on Youtube that are quite helpful. Having 64 GB of ram is really nice when using multiple programs at the same time. You can't go wrong with OWC. ... show more
